SPOUT FOR CONCRETE-MIXING MACHINES.

Application filed April 8,

T all whom it may concern:

Be it known that I, GEBHARD JAEGER, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented a certain new and useful Im rovement in Spouts for Concrete-Mixing achines, of which the following is a specification.

The special object of this invention is to provide in combination with a concrete mixing machine a distributing spout for the mixed material that can be both swung laterally and reciprocated longitudinally with the result that a more rapid, reliable and even distribution of the concrete is eflected.

The invention is embodied in the example herein shown and described, the feature of novelty being finally claimed.

In the accompanying drawing- Figure 1 is a view in side elevation of the invention.

Fig. 2 is a combined section and elevation taken on and. from the line II--II Fig. 1, looking to the right. Fig. 3 is a detail in plan View to illustrate the eccentric pitman or reciprocating rod actuated thereby.

In the views 5 designates the spout which receives the mixed concrete from a tiltable mixing drum, such for example as shown in my Patent No. 1,322,575, dated November 25, 1919, the discharge end only of the latter, being shown at 6. The 5 is supported at its upper and lower ends by pivoting legs 7 and 8 respectively upon bars 9. Both the bars and the upper legs 7 can be secured to pins 10 in the ends of a bolster 11 as best seen in Fig. 2. The bolster 11 is supported on the upper end of a spindle 12 stepped or secured in a socket piece 13 supported upon an extension 14 of the main mixer frame (not shown in detail). The bolster is provided with a set screw 16 at its middle to rest on the upper end of the spindle 12 and by means of which the bolster is adjustable up or down with reference to the parts on the spindle below the bolster. This set screw serves to keep the weight on the spout off the parts below the spindle. On the spindle 1921. Serial N0. 459,691.

12 below the bolster is an eccentric 17 connected to be rotated with a horizontal bevel gear 18; and driving said bevel gear is another bevel gear 19 having a horizontal shaft 20 journaled in a bracket arm 13 on the socket piece. The shaft 20 is driven by a. sprocket chain 21 conveniently taking power from the same source that drives the mixing drum (not shown). The eccentric 17 is equipped with a strap 22; and connecting said strap and the lower side of the spout is a link 23 so that when the eccentric is rotated the spout is reciproca'ted on its supporting legs 7 and 8. The lower end of the spout is supported by a bail 24 and a guy extending upward and attached to the upper portion of an upwardly extended main mixer frame as will be well understood. The bolster, the spout, and its supports 7 and 8. the bars 9,.and guy can all be swung by hand laterally or horizontally upon the spindle 12 and while the eccentric is being operated to reciprocate the spout longitudinally.

Because of the importance of having the mixing apparatus set low no great inclination of the conducting spout is practicable hence with this construction the mixed mass (which is often of a not very fluid character) is speeded to its place of deposit while being widely distributed by moving the spout horizontally.

The forms of the parts can be changed without departing from the gist of the invention as claimed.

\Vhat I claim is:

1. The combination of a distributing spout. eccentric means for reciprocating the same longitudinally and means for driving said reciprocating means adapted to permit horizontal swinging of the spout.

2. In combination. a distributing spout. a rotary bolster upon which the spout is supported to swing. an eccentric and its strap, a link connecting said strap and the spout and means for rotating the strap while the spout may be swung.
